Definitely Sam's luck will run out, it depends f it's one from each category (I feel it might be) but if it is I think it could be Holly or Rai-Elle for the girls and Sean & Connor or Cutkelvins for the groups, then obviously Matt for the overs, depending on the song choices and when they're put in the running order.

Ir depends on the performances I suppose and whether it's one from each category but I really fell that it's gonna be Grace as a shock or Holly tonight along with 100% Rai-Elle. I can't see Matt going just yet :/ I feel like Sam could scrape by yet again if is bottom 2 and not one from each category, but Cutkelvins or Sean & Connor going wouldn't be a shock at all as I feel both have ran out of steam (well Sean and Connor didn't even put the kettle to boil for the steam)
